Main performance and structure features:
Under the action of hot air heating and convection in the oven section, the separator film volatilizes CH₂Cl₂ on the surface, of which part of the gaseous state is condensed into liquid, part of the uncondensed tail gas is used as circulating drying gas, and the other part is discharged into the tail gas recovery system. We choose specially customized coconut shell activated carbon, which has the advantages of large CH₂Cl₂ adsorption capacity, high purification efficiency and good hydrophobicity. In the form of horizontal adsorption tank, the carbon loading capacity is large, the operation flexibility is high, the tail gas concentration of CH₂Cl₂ is less than 20mg/m³, and the recovery rate is more than 99.97%.
